Server memory kit for registered ECC platforms

This 32 GB kit contains two 16 GB DDR3 1333 modules built to PC3-10600 CL9 timings at 1.5 V. It is designed for workstations and servers that require registered ECC RDIMM modules and will not operate in standard desktop systems or alongside unbuffered memory.

240-pin registered DIMMs with dual-rank layout

Each module uses a 2Rx4 organisation and fits the standard 240-pin DDR3 socket. The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server configurations. No heat spreader is fitted, so airflow in the chassis must be sufficient for the bare PCB.

JEDEC and RoHS compliant dual-channel kit

The pair is tested together for matched performance and carries JEDEC and RoHS compliance markings. OWC supplies a limited lifetime warranty with an advanced replacement programme and free technical support, so a failed module can be swapped without returning the original first.

Questions about this item

What speed does the DDR3 1333 PC3-10600 interface cap at in practice?

The modules run at 1333 MT/s with CL9 latency, which is the JEDEC-standard ceiling for DDR3-1333 registered DIMMs.

What physical slot and clearance do these 240-pin RDIMMs need?

They require a 240-pin DDR3 RDIMM socket; the sticks have no heat spreader, so they fit in standard-height server DIMM slots without extra clearance.

How are the two 16 GB sticks installed for dual-channel operation, and what step is often missed?

Populate the two sticks in the matched-channel slots specified by the server manual, then verify in BIOS that ECC and registered mode are both enabled.
